Hi I just got a 620 and I don't really know where to check the trans / hydraulic oil. I found a plug on top of the rear end but can't find a drain plug.i put a new hydrolic filter on and would like to change the oil as well. Any info would be helpful thanks .

You have to remove the metal cover from the under side of the rig, runs from the engine to the trans/diff.

Then unhook the electric wire from the temp sending unit and remover the temp sending unit, at the front end of the trans/diff.

That is what my books tells me to do to drain it.

My 720 has a dipstick on the bottom of the square head fill plug on top of the rear end behind the seat.
